Description
AI generated. Afterglow Salvage is a complete short run browser survival game about gathering light in a dark arena. Your ship fires at nearby drones automatically while you control movement and a defensive phase dash. Survive six escalating waves and choose a build upgrade after each of the first five waves.
Seekers pursue, chargers telegraph a lunge, and spitters send visible projectiles. Choose from damage, firing speed, protective orbit sparks, salvage attraction, shield restoration and phase drive upgrades. Standard and Gentle modes offer different pacing.
Replay a named seed or the daily UTC seed, save a run file, restore it paused, and prepare an original PNG score card with the seed and difficulty. Graphics and synthesized effects are original. Everything needed for the browser game is included, with no service subscription or hosted multiplayer dependency.

Technologies
HTML, CSS, JavaScript, Canvas 2D, Web Audio API
Setup requirements
Open index.html in a current browser or serve the folder with any static web server. Choose a seed and difficulty, then Launch. Audio starts only through the sound controls or a deliberate launch with sound enabled. Save a run before closing. Run node tests.cjs for model checks.
Dependencies and ongoing costs
A current browser with Canvas 2D and JavaScript is required. Optional sound uses Web Audio. No external runtime library, paid API or recurring service is required. The static game can be hosted by the buyer; no paid hosting is included or purchased.
Known limitations
This is an independent browser game, not a Roblox experience or a native game engine project. It has six waves and one arena with escalating procedural encounters. Seeds reproduce the same initial challenge for the same version; movement and upgrades change outcomes. Score cards and checksums are local convenience records, not anti cheat verification. Saves are limited to 1 MB and do not persist automatically. Keyboard and pointer play are supported; motion, haptic, gamepad and network cooperative controls are not supplied. Gentle mode adds hull, slower spawning and seekers, and one hull restoration between waves. Sound output depends on browser and device permissions. AI generated disclosure appears in the game and listing.
